Saving (survey) data to a server location

Saving (survey) data to a server location

we have a laboratory with 20 workstations + one server. We'd like to save the data to the server directly instead of collecting it from the workstations.

Hypothetically all subjects answer the same survey and finish at the same time. Do we have to face any issues when 20 workstations try to write to the same "demographics.iqdat"? If so, how can we prevent this?
